The 4-0 start to the 2013 season has generated a lot of conversation around the city, and it may be making Kansas City a happier place to live.

"Sometimes the stars just align and you've got one of those magical seasons where everything is on your side and everything is working out for you," said Danny Parkins of 610 Sports Radio. "So far, it feels like that is happening in Kansas City."

Optimism is blasting through uprights and over the airwaves, a welcome change from the 2012 team that didn't take a lead in a game until mid-November and suffered through the murder-suicide of Jovan Belcher in December.

"It's night and day, apples and oranges, or apples and good whatever you want to say," said Parkins. "It could not be any more different."

For the first time in a long time, the talk on Kansas City's sports radio stations is flowing with good news.

"People want to talk about the positives," said Parkins. "This town is in a better mood on Mondays when the Chiefs win, so the shows have been very positive and people are receptive to that."

"If someone values a sports team, for example, and they're doing well, it's just like if we are valuing anything else in our life that is going well," said Jennifer Prohaska, a psychologist at the University of Kansas Hospital. "That improves our mood, so when we talk about groups of people doing well, the morale of our city improves as well."
